First accident I've ever had except for a little string slap when firsr learning how to shoot. Buddy and i were out at the cabin primarily to hunt rabbits, but took a little time to shoot our bows. Each take about a dozen shots at 20, back to 30 shoot, back to 40. Buddy takes 1 shot, then i put an arrow on my resr, attach release (hot shot vaper 4) and start to pull back. Not taking it very seriously im talking while pulling back and all the sudden BANG, my release goes flying who knows where the arrow is or if it exploded or what. I stand there for a second then my chest has this pretty sharp pain, spot of blood on my white shirt. No puncture wound, thank God. Here is what I think happened, not paying attention i didnt have a grip on my release and it slipped from my fingers still attached to dloop, arrow launched to wherever i happened to be pointed at at the time. The release smacks into the rest bouncing back and.flying a good ways before hitting a tree, my right hand flys back and i punch myself in the chest breaking my skin and making my bleed. After a minute or two of standing there like WTF happened, pick up my stuff and we walk to get buddies arrow and the target. On the plus side of this, i found my arrow, actually almost hit the target, only missed by like 5 feet.
